It was all too much, the information he was receiving. On top of realizing he had lost his family, only to be replaced with these Jedi and this Padmé who was not his wife, he was in a world full of new dangers that he did not understand in the least. Demons, heaven, and hell...words like that had little meaning where words like Force, Jedi, and Sith ran rampant. However, he was able to grasp the concepts of good and evil well enough, knowing them personally through his own experiences, to understand that this Lucifer was not a good thing.
"I can't!" He shouted, pulling away when she reached out to touch him. "Stay away!" He demanded, fingers itching with intense desire to destroy something. This was not his Padmé. He couldn't be comforted by her, not yet, when memories of her pregnancy were so fresh. Turning around, he breathed deep, trying so hard to calm himself with techniques that Obi-Wan, not Sidious, had taught him. Sidious had only taught him how to destroy and would have encouraged him now to do so instead. He almost did, lifting a hand toward a nearby tree, but calmness prevailed finally and he let his hand drop.
"You should go back, Padmé," he said, not knowing what else to do. "I need time." Anakin needed time to think over what he had learned and to figure out what he would do now. Sidious was not in this universe, the Force could tell him as much. With the exception of the darkness he could feel off some of those Force users that had confronted him over the primitive communication device, the Sith did not exist here. The rules of his old world did not apply anymore and would not apply again, unless they were able to get back.
And so he needed time to think, plan, and approach this with a clearer mind. His traitorous ex-Master would have been so proud of Anakin's conclusion, had Anakin not had the burning desire to kill him still. Turning around to face Padmé again, a throbbing sensation in his heart started up again. She may not have been the wife that he loved, but she was still the woman he had loved. "I'll come for you again, once I figure out my next step. Do not tell the Jedi I had come for you." Family or not, they had seemed wary enough of him that he knew they would have not approved of this meeting between Padmé and himself. He couldn't risk her not being able to see him again, when he finally figured out his next step.
